Where to buy best iphone waterproof case?

I have to say, i work in a steel factory, and i have my 5s and before that my 5 in an otterbox armor, its big and bulky, but at the end of the day when i go home theres not a speck of dust on my white phone, i will endorse this case anyday!! But when i get home it goes into my lifeproof fre for 5s and i love that as well, the one i had for my 5 was garbage but this one seems to be ok

What improvements did they make in the new one? They seem to be identical to me with the exception of the fingerprint scanner compatibility.
